Early verdict · Few reviews so far

What the gurus are saying

Lactic acid that exfoliates while also moisturizing is uncommon among alpha hydroxy acids, and this serum pulls off both benefits without tingling or irritation despite being notably potent. Reviewers consistently found it improved skin texture and helped fade discoloration over time, praising the balance between activeness and gentleness. The formula includes lavender and linalool, though neither creates an overwhelming scent.

"If you're more prone to pigmentation or actual discoloration in the skin, I really like lactic acid. This comes from fermented bacteria and there are some great options. This one from Biossance is super, super potent."

"When it comes to lactic acid, I really love this Biossance Squalane + Lactic Acid Resurfacing Night Serum. This feels kind of like a milky type of serum that you put onto your skin. It's not so strong that you feel like a tingle or anything like that. It just feels like you're getting this smooth, steady exfoliation on a regular basis. So I like to wear this right before I put on my moisturizer as like the last serum step of my routine."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Alpha hydroxy acids

Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
